As the first Scottish Lifeboat station in Fraserburgh celebrates its 150th anniversary this year, Phil Cunningham narrates the history of the RNLI in Scotland, servicing its 6,000 mile coastline. From the rowing boats of the early days through to the hi-tech vessels that the RNLI launch today, the bravery and the ups and downs of RNLI life are charted in this tribute to the men and women who volunteer to save lives at sea.
